[Animal experiments on the biomechanical vibration behaviour of the bulbus (author's transl)].

Mechanical vibration may have a detrimental effect on visual performance. This particularly seems to be the case if the natural frequency of the bulbus is excited. Experiments with animals were made with the aim of calculating the biomechanic transmission of vibration between the cranium and bulbus. Postmortem experiments using pig crania have shown that in vivo application of the method of sewing miniature accelerometers onto the cornea may be possible. Our experiments with monkeys gave typical resonance curves for the transmission of vibration of the bulbi with maxima between 25 and 31.5 Hz. Transferability of the results to the human eye is discussed.
